Sunny weather means picnics, camping, swimming, hiking, and
as many other outdoor activities as possible. But look outside on a
warm day. You might be surprised how many people covered up in hats,
scarves, and sunglasses religiously slather on gallons of thick, white
sunscreen. Believe it or not, sunshine is good for you. In fact, it just
might be the wonder drug you’re looking for.
The best-known benefit of the sun is Vitamin D, which a recent New
York Times article reminds us can help build bones and healthy joints,
strengthen the immune system and lower the risks of illnesses such as
diabetes, heart and kidney disease, high blood pressure and cancer. But the best way to get Vitamin D isn’t through popping a pill – it’s
by spending time out in the sun.
What’s the Big Deal about Vitamin D?
Vitamin D is naturally made by the body, but is not stored in the
body. Production of this vitamin is activated by one’s exposure to
sunlight. Individuals with an adequate amount of Vitamin D have been
shown to suffer less from osteoporosis and joint pain, to have slowed
effects of arthritis and pain, and to have averted certain types of
cancer. Not only is Vitamin D important to stay healthy, inadequate
levels can render your body vulnerable to any number of chronic
conditions.
Generally, as little as ten minutes per day, or approximately one
hour of sun exposure each week is thought to be enough to produce the
necessary amount of Vitamin D.
However, most people do not get even that amount of sun exposure,
which is why certain foods high in Vitamin D (fortified milk, eggs and
fish rich in omega-3 fatty acids) are recommended. Supplements and cod
liver oil are two additional sources of this necessary daily part of a
healthy diet. In addition, as we age, our bodies tend to produce less
Vitamin D, even with adequate sun exposure.
Why You Need the Sun
Moderation is key in most areas of your health. The same is true for
the sun, says John Jacob Cannell, MD, Executive Director of the Vitamin D
Council, which supports moderate sun exposure. “Fear of the fatal form
of skin cancer, malignant melanoma, keeps many people out of the sun.
The problem with the theory is that the incidence of melanoma continues
to increase dramatically although many people have been completely
avoiding the sun for years. We are not saying sunburns are safe; they
are not. We are saying that brief, full-body sun exposure… is a much
smarter thing to do than dying of Vitamin D deficiency.”
In the revelatory book, “Dark Deceptions: Discover the Truth about
Sun Exposure,” noted osteopathic physician and natural health advocate
Dr. Joseph Mercola reported that over 600,000 people around the world
are developing cancer because they do not receive enough sun exposure to
optimize their Vitamin D levels.
Factors that influence the amount of Vitamin D necessary for any
person are: geographic area, age, obesity, amount of melatonin in the
skin, and other factors. A simple blood test administered by your
physician or health care professional can identify the ideal amount of
this vital
nutrient essential for your individual health and well being.
What’s in Your Sunscreen?
If you were marketing a chemical compound laden with a plethora of
potentially harmful ingredients in a lotion, how would you sell it? By
telling everyone if they didn’t, they’d die of something worse, of
course. And lo, the sunscreen industry is born. Even though more people
use sunscreen than ever before, the incidence of skin cancer in the
United States and other countries continues to rise.
While the manufacturers are busily pointing out why you need their
product to stay healthy in the sun, they neglect to mention what’s in
their own concoctions. And the truth may surprise you. There are several
potentially harmful chemicals found in sunscreens that purportedly
advance the possibility of skin cancers. There are no fewer than four
known carcinogens found in popular sunscreen products. A number of
studies conducted in the 1990s report higher, not lower, incidence of
the deadliest form of skin cancer, malignant melanoma, among frequent
sunscreen users.
In a recently released report questioning the effectiveness and
safety of top-selling sunscreens, the Environmental Working Group (EWG)
claims that many contain potentially hazardous ingredients. In fact,
they evaluated 500 sunscreens and found only 8% to be acceptable. About
60% of sunscreens contain the chemical ingredient oxybenzone, which the
EWG considers unsafe because of concerns that it can penetrate the skin
and disrupt hormone balance.
The Light that Heals
In the end, it’s up to you to cut through the marketing hype and make
the right decision for yourself and your optimal health. Boost your
Vitamin D levels and increase your sun exposure to appropriate levels
that serve you and your well-being.
